In their recent draft of an endangerment-finding technical support document (TSD), scientists at the U.S. Environmental Protection Agency (EPA) conclude that carbon dioxide emissions are a public health hazard and should be regulated under the Clean Air Act. Federal law requires that regulations be based on scientific information that is “accurate, clear, complete, and unbiased”; the most recent available; and collected by the “best available methods.” The EPA’s TSD on carbon emissions violates all of these requirements.

Staff researcher Dr. Alan Carlin, given just a few days to review the draft TSD, took EPA to the woodshed because the report offered little more than a bibliography of out-of-date reports and research rather than a rigorous scientific inquiry into the subject. The Carlin report’s preface clearly shows that the EPA abdicated its position of scientific authority on the subject: “Our conclusions do represent the best science in the sense of most closely corresponding to available observations that we currently know of [and] are sufficiently at variance with those of the IPCC, CCSP, and the Draft TSD that we believe they support our increasing concern that EPA has not critically reviewed the finding by these other groups.”

Both of EPA’s recent attempts to regulate additional pollutants under the Clean Air Act have had poor results. [Read more →]

Now that the U. S. Environmental Protection Agency (EPA) has announced intent to find that greenhouse gas emissions (primarily carbon dioxide) from human activities lead to the “endangerment of public health and welfare,” the question arises: What could EPA theoretically do about it? (I’ll leave the politics to others.) In other words, can a U.S.-side agency conceptually protect U.S. citizens from the endangerment of their health and welfare from the global issue of  global warming?

It turns out that they cannot do much of anything. EPA is simply saber-rattling to get Congress’s attention. If the agency was forced to actually draw their weapon in battle, they would be holding a rubber sword against a massive and growing global force. The bottom line: the EPA is brandishing only about 0.0033ºC/yr-worth of global temperature influence—and that is only if it managed to shut down all greenhouse gas emissions from U.S. economic activity and keep it that way. All the while, the warming pressure from the rest of the world steadily grows, shrinking the EPA’s already too-small-to-matter arsenal.

This can be understood by simplifying the issue down to the Xs and Os—carbon dioxide emissions and global temperatures. [Read more →]
